Aluminum Welding Techniques MIG Welding (Metal Inert Gas)- supplies power to wire fed through the center of gas cone, heat and filler are the same. TIG Welding (Tungsten Inert Gas) or Heliarc – seperates the heat source from the filler material.

MIG Welding Shield gas is 100% Argon Faster than regular steel MIG welding, due to the higher thermal conductivity Material must be very clean for effective weld Good for long runs and heavy material

TIG Welding Shield Gas mostly Argon some helium Electrode usually tungsten Similar Brazing or soldering Cleans surface while welding, less prep than MIG Slower than MIG Good for thin metal, seals better than MIG, and usually more attractive depending on the welder

The TIG-welding process.
